The present invention rela test0 hinges in general, but is concerned 1n0re particularly i with hinges which perniit the arts hingecl cogether 130 b e rea clily taken apart; ancl the principal object is (0 provicle a new und. improved struct ancl cheap to manufactnre.

-ings, comprising Figs. 1-5, inclusive, Fig. 1

is 21 front view of the base 01 a boxwhit:h is provided with the improved hinges, the cover bei1ig removecl; Fig. 2 is arear view 0'f the removecl cover; Fig. 3 is a cross sect-i0n 0n line AAA through Figs. 1 ancl 2 Wih thecover in Place und closed; and Figs. 1

and are perspective views of a portionbf the base 2 ancl cover 3. v

Thebase 2 is a sheet 1netal stamping with a raised central Portion as"can be seen in Fig. 3. The slots 6 sind 7 cnt in the base 2 zu*e aclapted 130 receive the hinge 1nembers 4 ancl 5 which are nveted on the cover The: cover 3, wlnch also 1s macle of sheet metal hfis a box like shape zind is open" in the rear. 1n0rder to place the coyer 3 on. ehe base 2, the former 1s rotatecl from 1ts pos1tmn 111 Fig. 2 about an axis formed by a line run ni1ig; through the hinge 1nembers ancl 5 until the plane 0f the cover is approxnnately atiight angles t0 the plane 01 thefbase 2,

nt Which ti1ne the hinge members- 4: ancl. 5

a1ehow brought into .alignnnent With ancl insertecl 1nto the slots 6 ancl 7 as shown in F1g, -4. The cover 1s 1noved downwarcl Slightly cause the projections 17 und 18 of the hinge n1ernbers 4 anal 5 to come behind and below the lower edgjes' 0f tlie slots 6 ancl 7 as shwn in Fig. 5 so 215 to prevent the cover 3 .fronmbeing pullecl away from base 27 The catch 8 is now rotated about ite pivot in a counter-clockavism direction until the projection 19 thereof strikes t he" raised portion 10 of the base. In thiS posi'tion ehe catch 8 preve'nts the hinge 5 from moving up The cover 3 may now be swung shug,

the raisecl p0 rtions. 9 and 10 prevehting any binding that might otherwise e'ccui. When hingefofthe above Charcter {ahnt is j s 1 mple in constrnc t1on a ncl 1s eaSy 130 00117 the box is shnt theencl 0'f the locki1 1gto ngue 12 1s in the noteh 11 in the bqse anal serves 150 hold the box shnt by its spring actip11. The supp'erting pst14, which is most cleaifly seen in Fig'; 8 is serewedii1tothe Cover 3 a;ind preVents t h e tongi1e*l2 fronispringing 0 p en. The knoh 13 i's secnretl f0 the Cpvef 8 by a, holt ancliint'as-shown in Fig. 3 ancl serVes 2Ls a handle for 015en'ingand shutting ehe bo2g. 4

When the b0'21' is penecl .1he': over stopped, elfte? it has (urned about ninety clegrees, by the projections 17 an(l 18 0 n the hinges 1 und 5 as theycozne intoengageinent W1th the'base 2 at the loweir eclges 0f the Upn referring t0 Fi, in 3, it Will he ncifecl that the portion of the' basei2 which is engagec'l by the ecl e o f the c0ve13 is iormed 1nto an ;arc 0'f -a c1rcle over wlnchthe; snn1= larly 1O'I'I1le'd lnnges' 5 ancl 6 glide when the b0x isbeing 0Penecl 01 shut. The hinge 4,;

VVhe'n it is cles ired to rennove ehe cover 3- fromthebase2, it is necessary merely t0 open the l00x tothe 'fullest extent and then to'rotatethe catch 8 o ut of the pathof the hinge 5 after WhiCh the cover 8 1nay b'e 'easily pushecl up and then lifted off.
